The drawings illustrate the preferred form of construction embodying myinvention. By this construction the several objects of the invention areaccomplished.

In this connection the cooker is indicated at I5 and includes an innerenclosure I6 and an outer enclosure I'I. The side and back walls I8 ofthe outer enclosure each provide a space in which a suitable insulationI9 is packed.

The back wall 2U of the inner enclosure likewise provides a space inwhich an insulation 2I is packed.

The side walls 22 of the inner enclosure are spaced substantially fromthe side walls I8 of the outer enclosure, and mounted in the space thusprovided between these side Walls are horizontally arranged channels 23Closed at the corresponding end portions 24. In one of the side Walls 22of the inner enclosure I6 there are provided apertures or openings 25which open communication between the channels 23 and the interior of theinner enclosure I6.

p The. innerf enclosure is.L divided. into a pluralityotcompartn'ier-i.ta33:.I Thesefcompartments '33.' are. separated by gridplates 34 mounted upon supporting angles 35 secured to the walls of theinner enclosure as shown in Figs. 2 and 5. Each of the grid plates havea Wall 35 of ceramic material.

Below these grid plates are mounted burner structures 36 comprisingceramic plates 31 mounted upon supporting angles 38 carried by the wallsof the inner enclosure. These ceramic plates 31 are spaced as at 39 toprovide an air passage as indicated by the arrows in Fig. 2. Eachceramic plate has a depending portion 4I] disposed between the burnerpipes 4I which are perforated to direct the ame therefrom against theseceramic depending portions. These burner pipes are connected as at 42 toa branch supply pipe 43 in turn connected to a main supply pipe 45.

Corresponding inner ending portions 43' of these branch pipes aresupported by the Wall 20 of the inner enclosure (Fig. 3). Each branchpipe is controlled by a suitable valve structure 46.

Access to each of the compartments 33 is provided by suitable dooropenings 54 normally closed by doors 55. With the exception of the upperone of these doors 55, the remaining doors are of the drop type, thatis, hinged as at 56 from the bottom edge thereof to the front wall 45 ofthe outer enclosure l1. The upper one of these doors 55 is hinged as at5B from the side edge 59 thereof.

Slidably supported on each of the grid plates 34 is a follower 60 whichextends completely across the grid plate and is adapted to engage thepans or trays thereon and, when moved forward, to move such pans ortrays from the rear of the compartment to the forward end thereof forremoval therefrom.

This forward movement of the follower is accomplished by means of rod 6|having connection to follower 60, by means of suitable bearing 62 whichprojects through and operates in the elongated opening 21. The exteriorend 63 of this rod 6i projects through an opening 64 formed in the frontwall 45 of the outer enclosure. This rod 6I has an elongated V-shapedgroove 65 formed therein, and engaging in this groove is a V-shapedprong or tooth 66 carried by the plate B1 mounted as at 68 to the frontwall of the outer enclosure.

The arrangement is such that this prong or tooth 66, operating in theV-shaped groove 65, will maintain the rod and consequently the followerfrom turning about an axis during movement of the rod and follower. Bypulling rod BI outwardly, the follower 60 will be brought intoengagement with such pans or trays as are mounted upon the grid plate tomove the pans or trays to the forward end of the compartment forconvenient removal.

A cooker constructed in accordance with the foregoing descriptionresults in one having the maximum capacity. The construction permits thecooker to be placed in a confined or limited space, such for example inthe kitchen of a dining car where there is a limited amount of spaceprovided for cooking facilities. It is also apparent that a cookerconstructed in accordance with the foregoing description will be amplyinsulated so that the heat may be retained therein and yet the cookerhas ample and sufficient ventilation to carry off the fumes therefrom.

While I have illustrated and described the preferred form ofconstruction for carrying my in- I vention into effect, this is capableof variation and modification without departing from the spirit of theinvention. I, therefore, do not wish to be limited to the precisedetails of construction set forth, but desire to avail myself of suchvariations the plates, and means for moving the follower over the platecomprising a handle element extending exteriorly of the enclosurethrough an opening formed in a wall thereof and having a longitudinallyextending guiding groove formed therein, and a member carried by saidwall and Y provided with a prong extending into said groove.

2. An apparatus of the class described including an enclosure havingmeans adapted to permit circulation of air therethrough, means dividingthe enclosure into a plurality of compartments comprising spaced gridplates and burner structures spaced from the plates, a follower slidablysupported upon each of said plates for removing pans or the like fromthe plates, means for moving the follower over the plate comprising ahandle element extending exteriorly of the enclosure through an openingformed in a wall thereof and having a longitudinally extending guidinggroove formed therein, and a member carried by said wall and providedwith a prong extending into said groove.
